gium, have invented new and useful Imovements in Railway Trucks orWagons, of which the following is a specification.

This invention relates to improvements in railway trucks or wagons. r

The improved truck is of considerable and is intended for the transportof articles of great length such as rails, balks, etc- The essentialfeatures of the invention consist in the use of metallic cables in orderto strengthen and truss the side sills of the wagon; in-themethod ofapplication and of these cables on the side sills and in the articulatedsystem of buffers of the wagon. i

Fig. 15 is a lan view of the same. Fig. 16 is a detail pan view of the sector for sustaining the shocks and tractionapparatus.

The wagon consists. essentially of a platform 1?, supported by twobogies B.

The platformis designed to resist in the best possible manner thestrains arising either from the load, or from the workin conditions. Thesaid platform is forms by two side sills cross-pieces t. Each side sillcomprises a trussed beam composed of two channels Z, connected bycross-bars m of cast-steel; the retaining member is formed by metallic Fof Fig. 8; Fig. 10 is a lateral.

a longitudinal section.

cables of steel'n, n, of the kind which are used 1n m1nes,and byhanging-posts of cast-.

steel 0. The cables are arran ed in-the longitudinal axis of 'thesidesihs; their ends pass between the two channels Z and are xed, asmentioned further on, to the upper part of the side sill. In this mannera very strong frame-work is" obtained, the upper part of which forms abody which is capable of resistin the very great strains of compression,to shunting and the lower part of which is formed of cable of extra hardsteel, with a resistance of 120 kilogrammes per square millimeter. Theuse of this cable allows great lightness to be given to the whole.

The hanging-posts 0, sustaining the beam,

are movable at their ends; by this fact the side sills comply withoutany inconvenience to all movements which are due to flexibility orexpansion; therefore no deformation of this beam need be feared.

' Each end of the cable is inclosed in a steelpiece a, hollowed in theform of a truncated cone, in the interior of which the wires which formthe cable are unraveled, bent round at their end and embedded in a massof white metal. This piece a consists of two parts: The first a, of asquare shape, is fitted into ahousing provided at the upper part of across-bar of the side sill; the second, out like a screw along its wholelength, is capped with a screw-sleeve'b, lying on a fixed point of theside sill through the medium .of a washer r, applied on the cross-bar Bythis arrangement, the piece a cannot make: any rotating movement, and 1t15 sufiicient to turn the screw-sleeve b on itself in order to obtainthe horizontal displacement "of the piece a, and in consequence, of thecable which can be regulated as desired as regards the tension. In thismanner the inconveniences which the stretching of the .cables wouldproduce under the successive loads L, connected together by I can beovercome. From one cross-frame to another the hanging posts 0 areconnected two by two attheir lower part, by means of a bar whichmaintains the distance between t e hanging posts and the cables.

The hanging. posts 0 su ported by the cables are set according to thebi-section of the angle formed by the two bodies of these cables. Inorder to maintain them in this position it is necessary to arrange astop with its support on the cable without diminishing the strength ofsame by its mode of which are due to the load and anchorage. The adoptedarrangement (Figs. 8 and 9) comprises two pieces; the one 0 bears a heelwhich stops the cross-beam; it is threaded on a certain length and endsby a trunconical portion d, which is divided by a saw-stroke into fourthin plates forming a spring; the other is a sleeve e which is fitted inand screwed on the part 0. By

screwing this sleeve, the trunconical platesneighboring vehicles and incrossing strike 'onthe extreme cross-beams which they may break;further, the coupling books of two neighborin wagons become removedsomuch as to ren er the coupling impossible to .make. It results. fromthese facts, that wagons of great length cause damage to the couplingsand even cause derailment, and it is generally necessary to work themsingly. In order to avoid these inconveniences this invention provides asystem of articulated bufi'ers, with their support on the platform ofthe wagon and transmitting to the latter the shocks received, and arecapable of lateral displacement. This is done in the following manner:At each extremity of the wagon is a guiderail f in the form of a bow andfixed by means of supports 1- riveted in the side sills; a sector 9 ofcast-steel carrying theshocks and traction apparatus, is sup orted bythis ide rail; it slides on same y the interme ary of eight rollers s,and describes a circle round the axle of the pivot of the bogie u. Thissector g is controlled by a fork h extending from the pivot of the bogieand which isguided by a retaining member 1', fixed at the end of thisbogie.

When the wagon enters a curve, the bogie,

which is guided by the rail moves the fork h which by the intermediaryof two pivots 7' moves the whole system of buffers; this latter isdisplaced independently from the platform of the wagon, just as if itwere xed on the bogie. On very sharp curves these buffers projectsomewhat laterally of the side sills of the platform. Bearing plates isof cast-steel are strongly fixed on the side sills and take the strainof the shock when shuntin etc.

Having now described my invention, what I claim as new and desire to'secure by Let ters Patent is:

A railway truck comprising two bogies, a. platform, two side sills onwhich rests the .tom of said side sills, metallic cables of steelplatform and each of which is formed of two channels, cross-barsconnectingthe channels, cross-pieces connecting the side sills, hangingposts articulated at the bottorn ofsaid side sills, and metallic cablesof steel arranged in the longitudinal axes of the side sills and adaptedin combination with the hanging posts to strengthen and truss said sidesills, substantially as described and for the purpose set forth. 2.
